Patented Feb. 24, 1953 PROTECTIVE SHIELD FOR STOVE AND LIKE PIPE Eugene Janski, Chicago, Ill.

Application August 6, 1951, Serial No. 240,570

3 Claims. 1

The present invention relates to the shields for stove pipes and other like pipes for protecting surrounding objects from the high temperature of the pipe.

Another object of the present invention is the provision of a shield of a character indicated provided with struck out wings bent to a substantially perpendicular relation with the body of the shield, and which wings may be so formed as not only to act as spacers for the pipe with which they contact and the body of the shield, but also to direct the heated currents between the pipe and the shield in a lateral direction so as to derive from the pipe the greatest degree of heating economy.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views:

Fig. 1 is an inner face elevational view of the present shield;

Fig. 2 is a side elevational view thereof; and

Fig. 3 is a plan elevational view of the shield, showing the same in an operative position with a pipe, the latter being shown in a transverse cross section.

Referring to the present drawing in detail there is shown therein a shield I0 made out of a single rectangular sheet of material, preferably metallic, arcuately bent on a transverse cross section. The arc, however, does not conform to a circle, so that when the shield is in an operative position with pipe II, the edges of the shield are farther removed from the pipe than the central portion of the shield, as is clearly seen in Fig. 3.

Centrally, the shield is provided with a plurality of comparatively narrow and short wings l2 struck out from the body of shield 19, which remain in a mutual parallel and spaced relation longitudinally of the shield, as is clearly seen in Fig. 1. The free edges of said wings I?! are arcuate substantially conforming to the arc of the pipe. By these edges said wings 12 contact the periphery of the pipe, when the shield is in an operative position therewith, as seen in Fig. 3.

Above each wing l2 the shield is provided with a pair of oblique wings struck out from the body of shield It, each pair of said wings #3 extending in an upward, divergent direction, as is clearly seen in Fig. 1. The lower ends of said wings (3 are mutually spaced, the space however therebetween being smaller than the length of wing 12. At some distance downwardly from the lower ends of a pair of said wings :3, one wing I2 is located.

The upper ends of a pair of wings 13 extend almost to the adjacent side edges of the shield. By virtue of this arrangement heated currents generated below wings l2 and I3 will be deflected by said wings l3 laterally, and any heated currents passing through the space between wings l2 and i3 will rise upwardly to be defiected by the upper series of said wings l2 and 23, as is clearly seen in Fig. l.

The outer free edges of said wings l3 are made arcuate to conform to the are traced upon an oblique line of said pipe ll, so that the said outer free edges of said wings l3 may contact with the periphery of said pipe ll, thereby preventin the escape of heated currents past said wings I3.

Placed upon the outer face of the shield and in contact therewith, is asbestos sheet M. The side edges of shield H] are bent and brought forward to the adjacent body portion of the sheet adjacent the edges thereof, to define flaps !5, between which and the adjacent side body portions of the shield the marginal portions of asbestos sheet 14 are clamped and held in an operative position with the shield, as best seen inFig. 3.

The margins of shield It, asbestos sheet 14 and flaps [5 are provided with a plurality of registering apertures It for engaging the ends of one or more wires I I which encompass pipe H and constitute means for holding the device in an operative position adjacent the peripheral portion of the pipe.

From the hereinabove description it will be apparent that the shield herein devised not only acts as a protector against the heat emanating from the pipe, but also, through wings I! and I3, acts as a heat circulatory device adding to the heating economy, particularly when the shield is used in dwellings.

Each shield at one of its ends is provided with a plurality of spaced slits l8 for the purpose of defining a plurality of indents l9, which may be bent out from the plane of the shield for the purpose of engaging the adjacent end of another shield. By means of these indents l9 two or more shields may be connected in a longitudinal relation. By this means a number of shields may be interconnected longitudinally in order to protect a pipe of any length.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

l. A protective shield for stove and like pipes comprising an arcuate sheet, a plurality of wings struck out from the sheet substantially at right angles therewith, some of said wings being comparatively short and disposed in a mutual spaced relation and in a transverse relation with the sheet, the remaining wings being arranged in pairs, each pair being disposed above one of said short wings and in a mutually divergent manner, the edges at the free ends of all of said wings being so formed as to conform substantially to the curvature of the pipe when the shield is brought towards the pipe with the free ends of said wings in contact therewith, and mean for rigidly maintaining said sheet in a spaced relation with the pipe with said wings interposed between the sheet and the pipe.

2. A protective shield for stove and like pipes comprising an arcuate sheet, a plurality of Wings struck out from the body of the sheet substantially at right angles therewith, some of said wing being arranged in a mutually divergent direction with the divergent ends thereof disposed nearer to the side edges of said sheet than the inner ends thereof for the purpose of forcing the heated air between said sheet and the pipe to circulate toward the side edges of said sheet, when said sheet is in a normal operative asso- 4- ciation with the pipe with the free edges of said wings in contact therewith, and means for rigidly supporting said sheet in its operative association with the pipe.

3. A protective shield for stove and like pipes comprising an arcuate sheet, the curvature of said sheet being such that when such sheet is in operative association with the pipe the central portion of the sheet is nearer to the periphery of the pipe than its lateral edges are, the latter being in a greater divergent relation with the periphery of the pipe than the central portion of the sheet, a plurality of wings formed from said sheet substantially at right angles therewith, said wings having free ends adapted to contact with the pipe for forming spacers between said sheet and the pipe, and means for rigidly maintaining said sheet in a spaced relation with the pipe.
